Biosensor consists of an array of ultrathin graphene layers and gold structures.
The biosensing platform consists of an array of ultrathin graphene layers and gold nanostructures. The platform, combined with high-tech imaging (Raman spectroscopy), detects genetic material (RNA) and characterizes different kinds of stem cells with greater reliability, selectivity and sensitivity than today’s biosensors.
